This post is from the Activity iPhone Duo SwiftUI Q&A.
The Duo simulator boots showing only the outer display: the window is fixed at 382×644 pt and our layout classifier always reports the compact stack mode. We measured this on two separate clean boots (shutdown, erase, boot). xcrun simctl help lists no subcommand for folding, posture, or selecting the inner display — we read the full list. xcrun simctl io <udid> screenshot does reveal a second display (LCD-1, 2007×2853 px, aspect 0.70, close to the 669×951 inner portrait size). Unfolding manually in the Simulator UI works and the app then renders the two-column layout correctly, but we could not find a programmatic equivalent. Is there a supported way to unfold a Duo simulator from the command line or from XCTest?
